ERNST J. SWIEDOM, OF GIDDIN GS, TEXAS.

PLOW.

SPECIFICATION forming part of Letters Patent No. 436,273, dated September 9, 1890. Application filed December 12, 1889. fierial No. 333,445. (No model.)

To all whom it may concern.-

Be it known that I, ERNST J. SWIEDOM, of Giddings, in the county of Lee and State of Texas, have invented a new and Improved Plow, of which the followingis a full, clear, and exact description.

The object of the invention is to provide a new and improved plow which is simple and durable in construction and can be easily and quickly adjusted while the plow is running, and to increase or diminish the cut according to the nature of the ground to be plowed. The invention consists of certain parts and details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the improvement. Fig. 2 is an enlarged transverse section of the same on the line 00 x of Fig. 1. Fig. 3 is an enlarged plan View of the movable plate; and Fig. 4 is an enlarged side elevation, with parts in section, of the improvement as applied to a wooden beam.

The improved plow A is provided with the plow proper B, having the usual plowshare, landside, and mold-board, from which extends upward the stock 0, having its upper end 0' bifurcated, in which end the plow-beam D is pivoted, as is plainly shown in Fig. 1. On the rear end of the plow-beam D is formed a downwardly-projecting extension E, preferably standing at an obtuse angle to the plowbeam D. On this extension E, near the plowbeam D, are secured the handles F, and the said extension passes through an opening G, formed in a plate G, provided with a second opening G through which passes the stock 0 of the plow, so that the said plate G is guided vertically on the said stock. The plate G is also provided with a threaded aperture G in which screws the lower threaded end of a rod H, mounted to turn in suitable bearings I, secured on the plow-beam B between the extension E and the stock 0. The rod H extends parallel with the extension E and at an angle to the stock 0, and is provided at its upper end with a crank-arm J, arranged in such manner as to be easily taken hold of by the operator guiding the plow by the handles F.

As shown in Fig. 1, the plow-beam D is made of metal in one piece, while, as shown in Fig. 4, the p10 -bea1n D is of wood, the extension E being screwed on the under rear side of the plow-beam, as shown. The rod H passes through an aperture in the plow-beam D and the flange of the extension E, as is plainly shown in Fig. 4:, and is mounted to turn in the hearing I, secured to the top of the plow-beam.

The operation is as follows: \Vhen the several parts are in position, as shown in Fig. 1, and the operator desires to cut a shallower furrow with the plow proper B, he then turns the crank-arm J of the rod H, so that the latter raises the plate G, whereby the extension E is moved from the stock 0, and the front end of the plow-beam D is lowered, so that the team in pulling on the plow-beam causes the plow properB to out less into the ground so as to make a shallow furrow. When the operator desires to increase the cut of the plow proper B, he turns the handle J in the opposite direction to the one previously described, so that the rod H moves the plate G downward, whereby the extension E is moved toward the stock 0, and the front end of the plow-beam is raised. WVhen the team pulls on the plow-beam, the plow B now cuts deeper into the ground. Thus by the operator merely turning the crank-arm J he can increase or diminish the pitch of the plow, thus increasing or diminishing the depth of the furrow. By this arrangement much valuable time is saved, as the device can be operated by the plowman Without stopping the team, thus dispensing with the necessity of going to the front end of the beam in order to regulate the pitch of the plow by means of the clevis, thus also lessening the danger of being hurt by unruly animals, as has been frequently the case.

I do not limit myself to the especial construction of the detail parts as is shown in the drawings and described above.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the plow-beam having a downwardly-proj eoting extension or arm at its rear end and a plow-standard pivoted to the beam in front of said extension, of a plate connecting said standard and extension and adapted to slide vertically thereon and an adjusting-screw for operating said plate, substantially as set forth.

2. The combination, with the plow-beam having arearwardly-inclined extension E and 10 lunged plow beam 0, of a plate G, having slots G G through which pass said extension and standard, respectively, and a threaded crank shaft or rod H, sWiveled on the beam parallel with the said extension and engaging a threaded aperture in the said plate, substantially as set forth.
